[英]Heroku / Redis Connection error on Python/Django Project
I'm trying to set up django so it send automatic email when a certain date in my models i reached.我正在尝试设置 django,以便在我到达模型中的某个日期时自动发送 email。 However i setup a Heroku-Redis server and am trying to connect to it.
但是我设置了一个 Heroku-Redis 服务器并试图连接到它。 I created a simple task to test out if celery is working but it always returns the following error:
我创建了一个简单的任务来测试 celery 是否正常工作,但它总是返回以下错误:
Error while reading from socket: (10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None)
从套接字读取时出错:(10054,“现有连接被远程主机强行关闭”,无,10054,无)
I setup celery according to the website:我根据网站设置celery:
celery.py: celery.py:
import os
from celery import Celery
# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'incFleet.settings')
app = Celery('incFleet')
# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
# should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')
# Load task modules from all registered Django apps.
app.autodiscover_tasks()
@app.task(bind=True)
def debug_task(self):
print(f'Request: {self.request!r}')
Tasks.py任务.py
import datetime
from celery import shared_task, task
from time import sleep
from .models import trucks
from datetime import datetime
@shared_task()
def sleepy(duration):
sleep(duration)
return 0
#@shared_task()
#def send_warning():
My views:我的看法:
def index(request):
sleepy.delay(5)
return render(request, 'Inventory/index.html')
And my settings.py还有我的设置.py
# Celery Broker - Redis
CELERY_BROKER_URL = 'redis://:p0445df1196b44ba70a9bd0c84545315fec8a5dcbd77c8e8c4bd22ff4cd0a2ff4@ec2-54-167-58-171.compute-1.amazonaws.com:11900/'

CELERY_ACCEPT_CONTENT = ['json']
CELERY_TASK_SERIALIZER = 'json'
Heroku recommends using encryption and thus a rediss://
URL instead of redis://
Heroku 建议使用加密,因此使用
rediss://
URL 而不是redis://

After a while i realized the issue was with the network in my office.过了一会儿,我意识到问题出在我办公室的网络上。 The port i was trying to access was closed.
我试图访问的端口已关闭。 As soon as i activated redis on the actual server it started working fine.
一旦我在实际服务器上激活 redis,它就开始正常工作。
heroku config | grep REDIS
check the actual url using this code使用此代码检查实际的 url
